I have an 8800gt, I get solid 90fps with ET Wolfenstein, ioquake3, etc. all just fine. I just bought ETQW, installed via native installer of course and have been playing the game a bit. However no matter which resolution or settings I choose, the game behaves the exact same with regards to performance-- a constant 60fps cap and sinking between 30-60 here and there. The problem is that when capped at 60 on my LCD it has a tiny lag in movement. I had this problem in ET Wolfenstein and I solved it by turning the vsync off in the game and it sticks to 90fps now, plays like on my CRT.

Even using nvidia-settings to sync to my CRT and not LCD, the game is stuck at 60fps. Also, I just noticed in console this (in ETQW):

"vsync: SDL reports 178413976 - broken?"

EDIT: Nevermind, for anyone who has this game and runs into this, the fix is to edit your etqwconfig.cfg in ~/.etqw/base/ and add the following lines:
